1 Kings 2:8 NASB

[8] And behold, you have with you Shimei the son of Gera the Benjaminite, of Bahurim; now it was he who cursed me with a painful curse on the day I went to Mahanaim. But when he came down to meet me at the Jordan, I swore to him by the Lord, saying, ‘I will not put you to death with the sword.’
